For Exercise:

(a) Use a graph to estimate the solution set for the inequality. Zoom in far enough so that you can estimate the relevant end points to the nearest thousandth.

 Note: For natural numbers n, the symbol n! (read n factorial) denotes the product of the first n natural numbers. For instance, 3! = 1 × 2 × 3 = 6.
